Naot Oyster - The Oyster boot is from the Naot® Shell Collection, which runs as a Medium to Wide width. The Oyster is a pearl of a boot−a rare and beautiful find! Breathable leather and suede uppers with inside zipper for easy entry. Supersoft leather-covered footbed is comfortable and absorbs perspiration. Naot shoes feature an anatomical removable footbed that replicates an image of an actual foot, much like footprints left when walking in sand. Ultralightweight memory foam construction offers instant gratification and foot soothing comfort from the first wear.
